azure - 启动-AzVM : Cannot bind parameter 'DefaultProfile' when running an Azure runbook

Question

我正在研究这个official tutorial from MS Azure team运行 PowerShell Workflow Runbook 来启动 VM。但是当我启动以下 Runbook ( from step 6 of the tutorial ) 时，出现如下错误。 问题:我可能缺少什么，我们如何解决该问题？

备注:Start-AzVM来自Az.Compute module我已经导入了。

运行手册代码:

workflow MyFirstRunbook-Workflow
{
# Ensures that you do not inherit an AzContext in your runbook
Disable-AzContextAutosave –Scope Process

$Conn = Get-AutomationConnection -Name AzureRunAsConnection
Connect-AzAccount -ServicePrincipal -Tenant $Conn.TenantID -ApplicationId $Conn.ApplicationID -CertificateThumbprint $Conn.CertificateThumbprint

$AzureContext = Get-AzSubscription -SubscriptionId $Conn.SubscriptionID

Start-AzVM -Name 'vm-cs-web01' -ResourceGroupName 'rg-cs-ansible1' -AzContext $AzureContext
}

错误:

Start-AzVM : Cannot bind parameter 'DefaultProfile'. Cannot convert the "a76c7e8f-210d-45e5-8f5e-525015b1c881" value of 
type "Deserialized.Microsoft.Azure.Commands.Profile.Models.PSAzureSubscription" to type 
"Microsoft.Azure.Commands.Common.Authentication.Abstractions.Core.IAzureContextContainer".

看起来文档中存在错误，在这种情况下，应该使用 Set-AzContext 来设置订阅，而不是使用 Get-AzSubscription 来获取订阅，更改如下命令，就可以正常工作了。

workflow MyFirstRunbook-Workflow
{
# Ensures that you do not inherit an AzContext in your runbook
Disable-AzContextAutosave –Scope Process

$Conn = Get-AutomationConnection -Name AzureRunAsConnection
Connect-AzAccount -ServicePrincipal -Tenant $Conn.TenantID -ApplicationId $Conn.ApplicationID -CertificateThumbprint $Conn.CertificateThumbprint

$AzureContext = Set-AzContext -SubscriptionId $Conn.SubscriptionID

Start-AzVM -Name 'vm-cs-web01' -ResourceGroupName 'rg-cs-ansible1' -AzContext $AzureContext
}
